Speech And Language Disorders
Impairments of speech or receptive language. Speech disorders usually involved difficulties with articulation which can generally be improved or resolved with speech therapy, usually requiring treatment over months or years. Language disorders, on the other hand, often result in substantial learning problems, involving difficulty with language comprehension, expression, word-finding and/or speech discrimination. Treatment by a language therapist generally leads to improvement in functional communication skills, although treatment cannot be generally expected to eradicate the problem.
